11 Building and Maintaining Relationships EPA (HQ and Regional Offices) Tribal Coordinators RE-Power America Team Regional Energy Advisors Superfund Reuse/Revitalization Coordinators Brownfields Coordinators Superfund Remedial Project Manager (RPMs) Smart-Growth Office DOE/NREL Your Local Utility

12 Evaluating the Renewable Energy Resource The Memorandum provided: An overview of renewable energy industry in Arizona An overview of relevant State and federal standards A summary of site history and operations, status of the site clean-up, and facility physical assets Apache Powder Superfund Site - St. David, AZ 2008 Solar Energy Information Memorandum

13 Evaluating State/Federal/Utility RE Policies Memorandum also provided: An overview of U.S. renewable energy standards ( RES ) Summary of federal and state tax incentives Local utility incentives While tribes may not be able to take the credits, subsidiary companies created by developers may be able to take credits Apache Powder Superfund Site - St, David, AZ 2008 Solar Energy Information Memorandum

14 3. Site-Specific Analysis Assessing Site Suitability Identifying appropriate RE technology options Reviewing energy markets and incentives

15 Evaluating the Renewable Energy Resource Evaluate the quality of renewable energy resources Consider the quality of the resource at or near a site as a the first step in determining the potential for using a renewable energy technology. Undertake initial screening on site potential for: Wind Solar (PV and Thermal) Geothermal Biomass Average Peak Sun Hours (NREL)

16 Renewable Energy Technology Options Solar Solar thermal Photovoltaic (PV) Biomass Energy Biofuels Biopower Wind Geothermal Direct-use Utility Scale Source: PacificCorp Source: NREL

17 Utility PV: Installed Cost Estimates Solar Photovoltaic Technology Type Acres per MW Estimate d Facility Size (MW) Estimated Land Area Needed (acres) Estimated Capital Cost ($ 1000) Estimated Annual O&M Cost ($ 1000) Thin Film (fixed axis) $25,000 30,000 $ Crystalline Silicon (fixed axis) $30,000 36,000 $ PV Tracking $35,000 40,000 $900 1,100 Tracking PV panels follow the sun to allow for increased solar capture Fixed axis PV panels aligned to be south facing Source: SunCarrier Source: EPA

18 Mapping Site Suitability for Solar CSP Potential: 130 Total Acres Zone A = 70 acres Zone B = 25 acres Zone C = 35 acres PV Potential: 185 Total Acres Zones A+B+C = 130 acres Zone D = 15 acres Zone E = 20 acres Zone F = 20 acres Net PV and CSP Potential 185 acres

19 Renewable Energy Technology Options Concentrating Solar Power (CSP) Versus Photovoltaic (PV) Solar Technology Type Acres per MW Minimum Practical Acreage Site Needs Storage Capacity Estimated* Annual Water Usage CSP PV 3 8 acres / MW 4 10 acres / MW acres Large, contiguous, level area Yes Significant N/A Flexible No Negligible *Estimates can vary based on specific technology Apache Powder Superfund Site St. David, AZ Solar Technology Options

20 Technology Specific Analysis PV Solar System Output By Season 5 MW PV Array 3 MW Array Apache Powder Superfund Site St. David, AZ PV Output - Sizing to On-site Demand

21 Assessing Site Suitability Mine Area Overview 31,000 acres of total land 11,290 acres are on Navajo land 1,800 acres Navajo fee land 9,500 acres privately held 7,430 acres Indian Allotment lands McKinley Mine Site Gallup, NM Navajo Nation

22 Assessing Site Suitability Preliminary Screening Criteria Included: Areas with 5% or less slope (slope % tied to PV tracking technology) Proximity to infrastructure (on-site substations and wells) Site accessibility (roads, rail) McKinley Mine Site Gallup, NM Geospatial Analysis

23 Assessing Site Suitability Site Infrastructure 21 miles of railroad line on mine lands 8,500 feet of 115 kv power lines exist within mine area Three substations and one switching station are on site 5 water wells on site that provided water to the mining operation Some haul roads converted to 2-track roads after reclamation is completed McKinley Mine Site - Gallup, NM Infrastructure Assessment

24 Market Opportunities and Incentives Solar Incentives / Market Drivers Federal Incentives Business Energy Tax Credits (aka Investment Tax Credits (ITCs)) Clean Renewable Energy Bonds (CREBs) State Incentives Renewable Portfolio Standards (RPS) Commercial/Industrial Solar Energy Tax Credit Program Utility Incentives Up front incentives (Rebates) Performance-based incentives Feed-in Tariffs

25 Market Opportunities and Incentives State Solar Deployment Trends Assess growth of PV system installations from year to year Evaluating total PV capacity installed in a state relative to neighboring states or previous years In 2009, CA and NJ led the nation in installed PV capacity State 2009 Installed Capacity (MW) 2008 Installed Capacity (MW) 2007 Installed Capacity (MW) California New Jersey Colorado Arizona Hawaii New York Nevada
